Another way to think about fractions is to consider a group of items. The items do not have to be the same size. For example, in a group of children, we can talk about half of the group.
Here are some examples of how a write a fraction out of a group of items.
The top number (numerator) comes from the number of items you want.
The bottom number (denominator) comes from the total number of items in the group.
There are 2 animals cards and a total of 5 cards.
The fraction we want is 2 out of 5.
There is only 1 plant card and a total of 4 cards.
The fraction we want is 1 out of 4.
There are 2 vehicle cards (the car and the ship) and a total of 6 cards.
The fraction we want is 2 out of 6.
Use common objects to test your child. Let your child test you. This exercise also helps your child understand how to categorize objects. The first step is to make sure that the number of items in the group is the same as the number as the denominator of the fraction.
Use 3 items if you want a fraction like two-third.
Use 6 items if you want a fraction like five-sixths.
And so on.
